Symantec Web Gateway is a web security gateway appliance that protects organizations against web threats, including malicious URLs, spyware, botnets, viruses, and other types of malware, and provides controls for web and application use. Backed by the Symantec global intelligence network, the Symantec Web Gateway is built on a scalable platform that quickly and simultaneously scans for malware and inappropriate web content, ensuring that organizations can maintain critical up-time and employee productivity that can suffer when organizations come under attack.

Symantec Web Gateway is built on a real-time inspection engine that scans traffic on-the-fly, without the delays associated with proxy-based architectures. On top of this real-time engine, Symantec Web Gateway adds multi-layer defenses to block inappropriate or malicious websites, active content, applications file downloads, "phone home" traffic, and attacks.
